HINGE-CUTTlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 787,232, dated April 11, 1905.'

Application lled July G, 1903. Serial No. 164,456.

liiniingliain, in the county of Vai-wick, England, have invented certain new and useful lniprovenients in Hinge-Cutting hlachines, of which the following is a specilicatioii.

'lhis invention relates to a hinge-cutting machine, the object being to provide a device of this character for rapidly and accurately cutting hinge-blanks.

'l`he improvements will be hereinafter made clear by the aid of the accompanying' sheets of drawings, reference-letters being used to indicate the different parts.

Figure l is an axial section, and Fig. is aplan, of a machine coinprehei'iding features of the improvements, such machine being' specially designed for facing the ends of butthinge blanks. Figs. 3 and i are views similar to Figs. l and 2, showing the machine adapted for cutting the gaps in the knuckle parts of hinge-blanks. Figs. 5 to l0 are detail views illustrating modified constructions and ar-l rangements of cutters for acting' on different obiects.

ln this machine the cutter is spiral in respect of the axis and the work is concentric in respect of the axis.

'lwo cutters il and c are used, such being similar in formation and being non-rotating on a delinite axis supporting them, the said axis being also non-rotating in the central bearing /I of a circular table e, forming the base or bed of the machine, this base oi' bed being itself supported in some suitable inanner. 'l'he cutters are each an incomplete aetive convolution of a spiral, as will be clearly seen from Fig. 2, which shows the upper cutter ff. 'l`he active part of the spiral convolution isffi'j, while the inactive part isf' f/ f, this inactive portion enabling the blanks to be faced to be taken troni and fed into recesses or pockets i' of a work-carrier I, which is supported upon the bed or base of themachine to rotate, the said carrier having delinite bearing on the table e at f, and being turned by a worm-gear /:z l, driven in some suitable way. The recesses oi pockets f are provided in the carrier so as to be concentric with the delinite axis (I, the butthinge blanks being lield in these recesses oi pockets, so that their ends are acted upon simultaneously by the cutters f/ and c as the carrier rotates, the said cutters being spaced apart on the axis (I to the finished length of the butt-hinge blanks. lt will be quite obvious that the carrier may be supported and turned in various ways, the only important Yfeature in respectof it being that the recesses or pockets in it to carry the work must rotate ina path concentric with the axis 1I.

Each blank fed into the carrier/ is faced on both its ends and is withdrawn from the said carrier during one complete rotation of the said carrier. For instance, the blank It, Fig. 2, has inst been fed into one of therecesses or pockets, while the one, F, is just about to leave its particular pocket after having been faced on both its ends by the cutters rt and c, the blank to be faced being carried round by the carrier and gradually step by step operated upon bythe teeth of the cutters, this step-by-step operation being clearly represented by Fig. 2. 'lhe faced blank ii drops out of its recess or pocket by its own weight and drops down the guide-tube in, supported by the stationary table w, to conduct the said blank to a suitable receiver. 'lihe blank /i, which has inst been fed into thc pocket or the recess, drops onto a rest n, which is adiustably cai'ried at n within the table e, this rest extending from the point /i to the point F and being for the purpose of preventing the said blank dropping through before it is sufficiently in contact with the cutters r/ and c to hold it. The butt-hinge blank /i (represented in Fig. l) shows the position of the blanks with respect to the two cutters, its lower end resting upon the rest n, the cutters not vet having caught hold of it. lt will be seen that the blanks are fed into and are taken from the pockets or recesses at the inactive opposite portionsf f/ f of the cutters a and c.

The adaptation of the features as aforesaid in a machine for cutting the gaps in the knuckle parts of hinge-blanks is represented by the section Fig. 3 and plan Fig. 4. In this machine three cutters a', c', and s are mounted upon the stationary definite axis (Z, but the disposition of their active surfaces in respect of each other and in respect of the definite axis is the same as the two cutters in the machine, Figs. l and 2. Three cutters are used in this machine, because the hingeblanks require to have three gaps putin their knuckle portions; but it will be obvious that any number of cutters may be arranged in the manner defined upon the stationary definite axis (Z. In this machine the table e and workcarrier Z are substantially as in Figs. l and 2, the only important di'erence being that the pockets or recesses z" to receive the blanks are of different shape and formation. Inactive parts in the cutters a, c, and s are provided in much the same way as the similar parts in the cutters, Figs. l and 2. In this machine devices are represented for setting the pockets or recesses c" in the carrier; but the effect of these devicesvmay be otherwise obtained, and therefore they form no part of the present invention, particularly so as the carrierZ can be made interchangeable in any machine. The inactive parts of the cutters are really gaps in the cutters, and they may be made much more decisive, if such is necessary, in order to put the work into the machine and take it therefrom, it being understood thatthe operation of the work is commenced and finished in one rotation of the carrier. It will be understood that the workcarrier Zmay be stationary and the cutters made to revolve with the same result.

A sheet of diagrams shows different adaptations of the features of the invention hereinbefore described.

Fig. 5 shows how a cutter may be formed by an incomplete spiral convolution of separate cutters c2, 02, CZ, c, f5, g', c', and Za, leaving an inactive portion 2, the work-carrier Z revolving and the said cutters being stationary.

Fig. 6 shows how the active face of the cutter may be the inner edge Z2 of a ring 2f, the cutter being stationary and the work revolving, the said cutter having a gap or non-active part Z3 for the purposes as aforesaid.

In Fig. 7 the cutter Z3 is a revolving emerywheel 4or the like concentrically mounted on the axis rZ, while the stationary work-carrier i Z5 has a revolving spiral or like path 253 upon l it, which serves to force the articles ZL step by step into cutting contact with the emery-wheel, the said articles being by the spiral path made to slide in the pockets or recesses e" holding them.

Fig. 8 shows a stationary spiral cutter a* and a concentric rotating' work-carrier Z6, (Z being the deiinite axis. The articles are carried upon spindles I, which are causedto revolve as the work-carrier is turned by a stationary toothed annulus j' and pinions f2, these spindles rotating the Work with them, so that in this arrangement while the work is carried round by the carrier it also is made to itself rotate, this arrangement in a machine being useful for many purposes-such as, for instance, for machining a circular groove k3 in the work.

Fig. 9 illustrates a cutter a5 with an active spiral face a and also with an active helical face a7, CZ being the axis, this cutter being useful for various purposes of machining. The workl la* is carried by the carrier, as before referred to, and is operated upon both vertically and horizontally.

Fig. l0 shows the cutter concentric with the axis rZ, but having a helical active face as, if being the Work.

The stock or blanks to be operated upon may be fed to the machine in any desirable way.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a machine of the character described, the combination with a substantially con volute disk-shaped cutter, of a circular carrier for the articles to be cut, one of said parts being stationary and the other rotatable, the cutter having a recessed inactive portion on its periphery for the insertion and removal of the articles in and from the carrier, substantially as and for the purpose specified.

2. In a machine of the character described, the combination of a stationary and approximately convolute disk-shaped cutter, a rotatable carrier for the articles to be cut providedl with a circular series of pockets concentric with the center of the carrier to hold said articles, said cutter being recessed on one por-` tion of its edge for the insertion and removal of the articles in and from said pockets, and means for rotating the carrier, substantially as and for the purpose specilied.

3. In a machine of the character described, the combination of a stationary and approximately convolute disk cutter, a circular rotatable carrier provided with a circular series of pockets concentric with the center of the carrier to hold said articles, said cutter being arranged above the carrier and recessed on one portion of its edge for the insertion of the articles in said pockets, and means for rotating the carrier to successively present the articles to the convolute cutting edge of the cutter, substantially as and for the purpose specied.

4. In a machine of the character described, the combination with a disk cutter having a mutilated convolute cutting edge, of a circular carrier for holding the articles to be operated IOC IIO

In testimony whereotl I have hereunto set my hund 1n presence ovt' two subscribing wlton, one of said parte being arranged above the other anni in close juxtaposition thereto, und means for rotating one of said parte` to nesses. cuue the articles to be successively operated on hy the convoiute cutting edge of the cutter, Suhetantiziiiy as and Vfor the purpose Specitied.
